In hydroponics, plant strength doesn't just start with the nutrient solution, but with the roots' ability to breathe within a balanced medium. Qareen Groof Soil's natural, highly porous volcanic rock helps increase aeration around the roots, speeds up drainage of excess water, and supports the stability of the granular medium, giving the roots a more active and stable environment within granular medium hydroponic systems. The product is especially recommended in the 10–25 mm size, well-washed, for granular hydroponics and aquaponics, with short, frequent watering and monitoring of water and leachate quality.
